Freezing clicnets & BSOD throughout LAN - both Win 7 & XP clients

[klop]

Hi, just got into work and found we've a high percentage of clients (both XP Pro and win 7 Pro) freezing and some showing BSOD

 

Was at home and from what I gathered at first it was only affecting our Win XP Pro machines but since getting here have realised it is in fact both win 7 and xp clients

 

When I log in there is the Windows has recovered from a serious popup - which then points towards drivers

 

We use WSUS - no drivers are approved

With WSUS can we see a time and date to pinpoint when an update may have been installed by a client?

 

No users are admin - so they shouldn't have been able to install anything.

 

This begun yesterady with a couple of PCs it seems, but today has spread to a very high percentage.

 

Not feeling at my best today (was home sick!) so any pointers would be greatly appreciated!

 

Cheers

Ok, only thing at the moment that i can seethat may have installed to both OS's in the last couple of days are two security updates for .net framework 4

 

They are KB2604121 & KB2656405

 

Can't imagine they'd be blue screening our PCs but now uninstalling them on a client and see what happens.

Damn thing keeps crashing though mid way throuh!!

 

Cheers

Maybe its something with your AV? Maybe a dodgy update?
